(Production Possibility Frontier/Curve, PPF, PPC) Why can't things be free?

Why is the Production Possibility Curve (PPC) or Production Possibility Frontier (PPF) concave? What does increasing opportunity costs mean? When we increase production, why does it seem that we have to sacrifice more and more resources? What are the limitations to this economic model?
In addition, how does this PPC model illustrates the concept of opportunity cost? In what way does it show that resources are limited? Where are the points that show under-utilization of resources, full utilization of resources? Where is productive efficiency achieved? Can there be more than 1 productively efficient point? What is the difference between productive efficiency and allocative efficiency?
Assumptions to this model:
We assume that there are only two types of goods produced in this economy.
We also assume that technology does not change.
This economic model is no doubt an oversimplification of how the real world works. So what are the implications?

    You know why this video can be a little confusing let alone the accent? Because the production possibility curve can be a straight line!!! A straight line production possibilities curve shows a constant opportunity cost if we compare corn and wheat, since the resources to produce corn and wheat are very similar!!! Whereas a bowed-out curve shows increasing opportunity cost, the resources to produce bread and the IPAD or whatever are completely different, that’s why it is concave!!!

    Thanks a lot for your compliment! You've really encouraged me to continue to make videos =). I used Adobe After Effects (animation), Illustrator (illustration) and Audacity (sound editing) to make the video. I read some books on design and writing to get inspired as I'm not an artist by training. I'm trying hard to learn design but there's really a lot to learn...I'm kind of overwhelmed...Thanks a lot for commenting..that's awesome=)

    Well, let's take your classmates in your class as an example. Some will be good at writing, some at sports, some at programming etc. Suppose your teacher needs to create a software. Naturally, she'll pick the guy most talented in programming to do the job. This one guy is very talented and hence he'll be really productive. Think about 1 Mark Zuckerberg beats 100 mediocre programmers. What if she needs more people? She'll pick the 2nd best guy, so on and so forth. Sooner or later she'll run out of programmers. If she needs more people, she'll have to pick from the remaining pool of people in the class, who are talented in other things like sports and arts but not programming. So these people, if chosen to program, will be far less productive than the first guy that she choose.

    This very old, I know. But in case anyone else stumbles has this question. The simple answer is because the resources often are not fully cross compatible. You may have some specific resources/technology that will increase your production of one good, but not the other. This causes the line of possible production between the two to be uneven. Hence the curve.

    in this example he mentioned that people have different skills, in order for it to be a straight line, everyone would have to have a phd meaning that everyone would be as efficient as can be, but as we know not everyone has a phd, therefore more and more people are required to do the same job.

  • @51MontyPython

    Since it takes more and more people to make more of one commodity (in this case, tablets), and because as more of the most skilled/efficient human capital (people) are required then to increase production by x amount, and a greater amount with each and every increase of the same amount, and since there is only a finite amount of human capital, in order to add more to one field, you must take away from another, and specifically, you must take away _more_ people for each and every increase even of the same incremental amount, than the same numerical increase prior to the next (or current one), and same for the increase prior to that, and prior to that, etc. For the first increase in tablets of x amount, it didn't require as many more people as it will for the same increase after so many of the most efficient people are taken up (for such endeavor), leaving you with a smaller pool of less and less efficient people (increasing production costs per unit). Hope that helped without confusing you more.

    Why can’t I just keep hiring the highly educated people to keep making the tablets? Is it because their salaries will become more expensive or there won’t be people like that available on the market anymore? Bc if there are people wanting tablets there then we could pay their salaries. And also there’s a bunch of people looking for jobs.

    It's just a hypothetical example where we are assuming that labour, capital, level of tech are constant.LLets make an exception and work with your example- Even if we automate machines, we would still need more machines (i.e. more capital) to produce bread (those which you will automate), and more economic resources result in the shift of the PPC, which is well explained within this theory. So, the economic model of PPC will still somewhat stand the test of your question.
